    En Route Decision Support Tool (EDST) is an integrated function of ERAM that is used by the sector team in performing its strategic planning responsibilities. EDST uses current plan data, forecast winds, aircraft performance characteristics, and track data to derive expected aircraft trajectories, and to predict conflicts between aircraft and between aircraft and special use or designated airspace. It also provides trial planning and enhanced flight data management capabilities.

    NOTE: For use by the EDST, the current plan is what the En Route Automation System (EAS) predicts an aircraft will fly. This may include clearances that have not yet been issued to the aircraft. Current plans are used to model a flight trajectory and, when applicable, for detecting conflicts.
